The purpose of this study was to evaluate the natural history of partial rotator cuff tears, especially a bursal side tear. 22 cases which were clinically diagnosed to have bursal side partial rotator cuff tears and had undergone MRIs twice. The average age of the patients was 68 years old, ranging from 42 to 86 years old. T2 weighted images were obtained along the oblique coronal plane and we evaluated the changes of high intensity in the rotator cuff in MRI. We compared the group with an enlargement of the tear size and the no-enlargement in age, sex, activity, dominant hand, smoking, and the shape of the acromion. Eleven cases (50%) showed an enlargement of high intensity. There was no correlation between the follow-up period and the enlargement size. Seven cases (32%) had become complete rotator cuff tears. There are no statistical differences between the enlargement and no-enlargement groups. This study showed that bursal side partial rotator cuff tears can enlarge in many cases.
